An observational study in Prostate Cancer, sponsored by University of Miami. Recruiting at 1 site in United States. Open to male participants aged 30 Years and older. Per ClinicalTrials.gov, last updated 2026-03-04.
Sponsored by University of Miami · Observational
The purpose of this research study is to learn about: 1) How standard radiation treatment to prostate (primary radiotherapy) or the pelvis after prostatectomy (postoperative radiotherapy) may cause changes in MRI and PET imaging traits that might be used in the future to predict response. 2) Comparison of such MRI and PET imaging traits with the number of circulating tumor cells (CTCs) present in the blood prior to treatment and the changes in these counts after treatment. 3) How MRI and PET imaging characteristics and changes are related to the expression of genes in the cancer tissue obtained before treatment from prostate biopsy or a prior prostatectomy before treatment. 4) How the response of prostate cancer treatment relates to the imaging and CTC changes.

Inclusion Criteria:
By imaging or clinical criteria, any patient with disease staging of N0/N1 and M0/M1.
Androgen deprivation therapy (ADT) is at the discretion of the treating physician, but must be declared as none, short-term, long-term, or extended prior to enrollment. The length is calculated from the LHRH (agonist injection). If ADT is planned (based on treating physician preference), the following restrictions apply:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Participants with prostate cancer diagnosis who are scheduled to undergo radiotherapy (definitive or palliative) with or without the addition of Androgen Deprivation Therapy (ADT) will be evaluated
Participants with prostate cancer diagnosis who are scheduled to undergo prostatectomy will be evaluated.
Comparison of Pre- and Post-Treatment Quantitative Imaging Parameters to Changes in Circulating Tumor Cells Over Time in Study Participants.
Pre-Treatment and Post-Treatment quantitative imaging parameters will be associated with circulating tumor cell (CTC) changes over time in prostate cancer (PCa) patients who receive treatment with RT ± androgen deprivation therapy (ADT) or prostatectomy per standard of care. CTC and quantitative imaging changes will be determined at each of the planned research acquisition time points (8 days prior to completion of radiation therapy (RT), 3 months post-RT, 9 months post-RT, and 2-2.5 years post-treatment) comparing to the Baseline.
Time frame: Baseline, within 8 Days Prior to End of RT, 3 months Post-RT, 9 months and 2-2.5 Years Post-RT
Relationship of CTC changes and/or quantitative imaging parameter changes to patient outcome (biochemical and clinical disease failure).
CTC changes between baseline and 2-2.5 years will be compared with 2-2.5 year biopsy positivity status (positive vs. negative) for patients whose baseline and 2-2.5 year biopsy samples are available. CTC changes from two different time points will be tested for significance using t-test by 2-2.5 year biopsy positivity status. Correlation structures between CTC and imaging parameters will be analyzed using linear mixed-effect model by 2-2.5 year biopsy positivity status.
Time frame: Between Baseline and 2-2.5 Years Post-RT
Relationship of Androgen Deprivation Therapy (ADT) status to quantitative imaging features and/or CTC levels in patients
Change of CTC and imaging parameters at a specific time point from baseline will be compared by ADT status (yes vs. no) using t-test. Correlation structure between CTC and imaging parameters will be analyzed using linear mixed-effect model by ADT status.
Time frame: Between Baseline and 2-2.5 Years Post-RT
Relationship of quantitative imaging characteristics and/or CTC changes with other tissue biomarkers obtained from the pre-treatment MRI ultrasound (US) fusion guided prostate biopsy or prostatectomy tissue in those treated primarily.
Gene expression data obtained at baseline will be analyzed in order to investigate the relationship between the gene expression and the following: CTCs, mpMRI imaging parameters, histopathological tumor parameters, and biochemical/clinical failure. CTC changes between baseline and 2-2.5 years will be compared with 2-2.5 year biopsy positivity status (positive vs. negative) for patients whose baseline and 2-2.5 year biopsy samples are available. CTC changes from two different time points will be tested for significance using t-test by 2-2.5 year biopsy positivity status. Changes in gene expression and imaging parameters will be analyzed in the same manner. Correlation structures between CTC and imaging parameters; CTC and gene expression; and imaging parameters and gene expression will be analyzed using linear mixed-effect model by 2-2.5 year biopsy positivity status.
Time frame: Between Baseline and 2-2.5 Years Post-RT
Comparison of changes in CTCs to endpoint prostate research biopsy status.
In patients who have undergone the MRI-US fusion guided biopsy (MUFgBx) at 2-2.5 years after all planned treatment, to investigate the relationship of circulating tumor cell (CTC) changes with the endpoint of research prostate biopsy status (only for those who are treated primarily with RT, who are not on indefinite ADT and who agree to this prostate early "endpoint" biopsy).
Time frame: Between Baseline and 2-2.5 Years Post-RT
Comparison of changes in quantitative imaging characteristics to endpoint prostate research biopsy status.
In patients who have undergone the MRI-US fusion guided biopsy (MUFgBx) at 2-2.5 years after all planned treatment, to investigate the relationship of quantitative imaging characteristics with the endpoint of research prostate biopsy status (only for those who are treated primarily with RT, who are not on indefinite ADT and who agree to this prostate early "endpoint" biopsy).
Time frame: Between Baseline and 2-2.5 Years Post-RT
Comparison of changes in gene expression patterns to endpoint prostate research biopsy status.
In patients who have undergone the MRI-US fusion guided biopsy (MUFgBx) at 2-2.5 years after all planned treatment, to investigate the relationship of pretreatment biopsy tissue gene expression patterns with the research endpoint of prostate biopsy status (only for those who are treated primarily with RT, who are not on indefinite ADT and who agree to this prostate early "endpoint" biopsy).
Time frame: Between Baseline and 2-2.5 Years Post-RT
Determination of the added value of PET/CT using newer tracers to MRI
PET/CT using newer tracers (fluciclovine, prostate-specific membrane antigen (PSMA), or Choline) to MRI may add value in the above secondary analyses. The investigators hypothesize that targeted PET agents will enhance the rate of accuracy of mpMRI in establishing high risk areas in the prostate, prostate bed, and pelvic lymph nodes, as well as provide unique information on early metastatic disease.
Time frame: Between Baseline and 2-2.5 Years Post-RT
